FOLDING CARD.

- Specification of Letters Patent.

A Patented Nov.26,1912.

Application filed March 2, 1912. Serial No. 681,149.

that in the act of unlocking, a printed or written message may be turnedinto view beneath the eye of the addressee or operator. In the drawings:Figure 1' is a front view of my new card, in locked relation; Fig. 2 thesame, unlocked, inner view; Fig. 3 15 a View of the locking disk; Fig. 4is a rear view of art of Fig. 1; and Fig. 5 is an edge view of ig.1.

As shown'in'the drawings, my new card consists essentially of two partsA and B,

hinged'together at one ed' e 0:, so that the two parts may be foldtogether. The front sheet A has an opening or sight, a and may ifdesired have additional sights,

as a. Interposed between the two parts A and B, and pivotally connectedto the front sheet A, at d by an eyelet or the like, is a revolublemember D,- having a tongue .11, preferably integral therewith, thetwosides of which are respectively parts of concentric circles about thepivot d. In the other member B, of the card, are two slits,'formingbetween them a bar 6, which lies across the path of the locking member(1 as the member D is rotated, so that, by slipping the point or thefree end of the member d under ar 6 and rotating the art D, the twoparts A and B may be secure y locked together.

It will be obvious that the side of the part D, which is o posed to thepart A, will be visible throng t e mem s-awa ns,

in the part A, and the part D may bear printed orwritten matter to beexposed as D is revolved. In the drawings I have shown one application,in which, when the card is locked, for mailing,the front shows nomessage, but as D is rotated to unlock the card, the message will bediscovered (see Fig. 1).

In the preferred "form, shown in the drawings,the locking member isformed as a disk and is secured to the card at such a position that itslower edge projects, so that the disk may be turned by taking hold ofthe lower, projecting ed e.

.It will be -o vious that the part D may be secured to the rear memberand the bar b, secured to the front member, if desired.

I claim 1. The folding card above described, comprising a front and arear member, a locking member having display matter thereon, pivotallysecured between the front and rear members and .a bar upon the member towhich the locking member is not secured, to

engage the locking member, said front member being apertured to disclosethe display -matter when the locking member is revolved,

all combined and operating substantially as described.

2. The locking device above described,

comprising front and rear members; a lock-
